Hello ,
This comment is sent from the SVG WG.
In 9.1.1
There is at most one viewport per canvas, but user agents may render
to more than one canvas (i.e., provide different views of the same
document).
http://www.w3.org/TR/2005/WD-CSS21-20050613/visuren.html#viewport
Its not clear whether this conflicts with SVG or not. Maybe if they said
that CSS establishes only a single viewport, it would not then appear to
conflict with graphical systems where multiple viewports are common.
